A pipeline sensing tool of a synthetic resin pipe is provided to facilitate drawing work for extending the length of a pipeline sensing line by winding the pipeline sensing line in a housing and to cut down the production cost through a simple structure. In a pipeline sensing tool(100) of a synthetic resin pipe, housing has a drawing part cut at one side, opened upper and lower parts, and a support piece bent inward at the lower end. A rotating body is placed in the housing and provided with a drawing hole perforated through the center and a cut portion formed at one side of the lower end. A lower end of the rotating body is supported by the support piece. A pipeline sensing line(30) is wound in the rotating body several times. A jack(31) drawn from the drawing hole bored in the center is connected to one side of the pipeline sensing line. The other side of the pipeline sensing line is connected with a connector(32) drawn from the drawing part cut at one side of the housing.
